IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 116,843, dated July l1, 1871.

To all 'whom it 'may concern.-

Be it known that I, FRANcIs MARION CHEsv TER LILEs, of Roanoke, in the county of Randolph and State of Alabama, have invented anew and Improved Horse-Power; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the `accompanying drawing making part of this specification, in which- Figure l,plate 1,'is a plan view of the machine complete. Fig. 2, plate 2, is a section taken longitudinally and vertically through the center of the machine.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to improvements on that class of horse-powers wherein two master-wheels are employed in combination with pinion-wheels, which transmit rotary motion to a shaft on which a belt-wheel is applied. The object of my invention is to combine, with machines of the abovenamed description, certain devices, hereinafter set forth, which will diminish friction, and which will also allow an adjustment of the spur-wheels to compensate for the wear of the teeth thereof.

The following description of my invention will enable others skilled in the art to understand it.

In the accompanying drawing, A A' represent two horizontal beams, which are arranged one -above the other and sustained by standards at their ends, so as to constitute a strong frame for sustaining the principal wheels ofthe power. B B are horizontal sill-beams, which are firmly secured to the sill-beam A, and extend out therefrom to a transverse beam, B2, upon which latter is applied the outer bearing p2, for the beltdrum shaft T. B1 represents a platform or bridge, which is secured across the outer portions of the converging beams B B, over which the animals are hitched to the sweeps S. L, L1, L2, and L3 represent beams which are strongly secured together and confined to the sill-beams B B, forming a frame for supporting one end of a shaft, G1, and also an anti-friction flanged roller, k. At the middle of the length of the beam A', and secured firmly thereupon, is plate, e, from which rises perpendicularly a shaft, E, around which turns a horizontal master-wheel, D, having` spur-teeth ay applied to its lower sides, as shown in Fig. 2. On top of this wheel, and extending diametrically, is a beam, C, which is secured down upon blocks and stayed by bra ce-rods o. To the ends of this beam C loops S' S' a-re applied for receiving and holding the sweeps S'. The shaft E passes through the beam C and receives a nut on its upper end. Directly below the shaft E is a turning-shaft, E', on which is secured a large wheel, D', having spur-teeth b secured to the lower side of its rim and a spur-wheel, F, of considerably less diameter, secured upon its spokes. This wheel D' is between the two horizontal beams A A', as shown by Fig. l. The teeth a. of wheel D engage with the teeth of a bevel-pinion, J, which is keyed on the sha-ft G', and the teeth of wheel F engage with another wheel, G, which is keyed on the shaft G'. The teeth I) b of the wheel D' engage with a pinion, V, which is keyed on the shaft T of belt-pulley R. By this arrangement of large and small wheels a comparatively slow motion imparted to the wheel D will transmit a very rapid motion to the belt-wheel R. The shaft G' is supported by journal-boxes g g', the latter one of which has a socket formed in its ca-p, which receives the lower end of a flanged roller, k, the upper end of which is received into a socketed box inserted into the cross-beam L, shown in Fig. 2. The ange K of roller-7c extends over the rim of wheel D, and holds this wheel down in place so that its teeth a will not sp1-ing up from the pinion J. The teeth b on wheel D' are held down in gear with the teeth of pinion V by means of a roller, H, which is applied to turn freely on the shaft G', and which is held up in place by a collar, Q, on this shaft. A yoke, y, is secured down upon the cross-beam L3 by means of nuts,`whicl1 are applied to upright screw-shafts j', and through the yoke a screw, y', is tapped, the end of which is s et up against the outer end of shaft G'. By means of the screw y' the shaft G' can be adjusted endwise, and the spur-wheels J G set up to their respective wheels, and any wea-r thereof compensated for. The cross-beams L L1 L3 are tied together by means of vertical screw-rods on, which nuts a n are applied, by means of which the intermediate beam L3 and the beam L can be adjusted vertically, to compensate for the wearing away of the pressure-rollers k H.

My object is to employ wheels D D' of very large diameter, in combination with pinion-wheels of small diameter. To do this and produce a practical m achine it is necessary to employ anti-friction lpressure-rollers, so arranged that they will prevent the large Wheels from springing up out of place With respect to the pinions With which they are engaged; and it is also necessary to provide means for adjusting said parts so as to compensate for Wear; Otherwise the machine will Work hard and irregular. These requirements I have fulfilled by the devices which I have above set forth.
